LOS ANGELES (CBS) — Temperatures again climbed into triple-digit territory in valley areas of the Southland Tuesday.

“The hot temperatures combined with very low humidities will bring elevated fire weather concerns to the interior portions of southwest California” much of this week, the National Weather Service said in an advisory, blaming the heat wave on a strong upper-level high pressure system centered over the Great Basin.

Temperatures are expected to range between 102 and 110 in the Antelope Valley and between 92-107 in the Santa Clarita and San Fernando valleys as well as mountain areas at low elevations, according to an NWS advisory.

Some monsoonal moisture is expected this week, creating a “slight chance” of afternoon and evening thunderstorms in mountain areas and the Antelope Valley from Wednesday through Friday, according to the weather service, which said the threat of lightning would increase fears of wildfires.

Anyone planning to spend time outdoors this week should stay hydrated and avoid strenuous activity, according to the weather service.

The NWS forecast highs today of 74 at LAX; 75 in Avalon; 77 in Newport Beach; 85 in downtown L.A.; 89 in Long Beach; 90 in Anaheim; 93 on Mount Wilson; 95 in San Gabriel; 98 in Burbank and Pasadena; 105 in Woodland Hills; 106 in Palmdale; 107 in Saugus; and 108 in Lancaster. A cooling trend will begin Thursday and accelerate on Friday.
